i dont think there are new post agents...and the type of programs that will do this are done by companies without much back so you'll never find a mac program.
I know there is another one i found on download.com a couple years ago but it wasnt quite as good and its so hard to spam newsgroups these days...they only let you send like one message per 5 minutes and they have all these things to detect what they consider spam and if they figure that its spam they delete all your past messages....
Better ways of making money...plus its risky which i failed to really see when i was 17
